Section 5 • Integrated Disease Management
learning objectives
• To develop a conceptual definition of a plant disease by individually sharing ideas and
experiences among participants and facilitators;
• To create awareness and appreciation among participants on interrelations of environment,
pathogen, and host in development of vegetable diseases; and
• To improve farmers’ decision-making skills through better understanding of disease triangle
equivalence theorem.
materials
• Organic vegetable fields with standing crops that are infected with diseases;
• Office supplies (e.g., Manila paper, masking tape, stapler, crayon, marking pens, record book,
pen, and chalks); and
• Others (e.g., plastic bags and plant disease samples).
methodology
• Field walks, role-playing, and brainstorming
steps
For Field Walks and Brainstorming Exercises:
1. Start exercise by conducting field walks and observations in organic vegetable fields with
standing crops that are infected with diseases. Ask participants to undertake following:
5 Each small group collects diseased organically-grown vegetables in learning and adjoining
fields;
5 Note down crop stand and factors in surroundings that may have favored occurrence of
diseases in learning and adjoining fields;
5 List down all observations related to spread of diseases among plants within a field and
between vegetable fields; and
5 Return to session hall or shade and process observations in small groups.
2. Formulate and distribute discussion guide questions for each small group to answer based on
their field observations;
